I've tried to tell X to use the fifo /dev/gpmdata as its pointing device but it doesn't work. The mouse behaves fine under gpm (even cut&paste works) but is unuseable under X. The mouse cursor does move when I move the mouse, but in completely erratic and unpredictable ways. The only way I've got the mouse to work under X is to not use the gpm fifo, and to stop gpm before starting X. My mouse is a Logitech 3-button PS/2 type. -chris
